The dsm failed emissions because their computer could not fully connect with my ecu. There was continuity, but couldnt talk to the ecu. Im able to connect with my lap top fine. Im tuning with ECMlink v3 full. Any ideas what to do?

Try a different emissions place.
Was just at the addison one lol. I stopped at autozone beforehand just to have them check to see if they caught anything on theirs. And they couldnt connect either. But I thought the guy was being a chicken shit and didnt want to touch anything.
Could be the port under dash.happened to me
FWIW the Joliet emissions place has a self serve terminal. Kinda like an atm machine for emissions testing. Worth trying.
I had my lightning tuned...had emmison test...vehicle didn't register as all systems were turned off. Had to put back to stock
